A bicycle is traveling at 20 miles per hour.

Luden [163]

Answer:

Step-by-step explanation:

Given the conversion 1mile = 5280feet

If a bicycle is traveling at 20 miles per hour, then the bicycke must have been travelling at (20*5280)feet per hour which is equivalent to 105,600 feet per hour.

To know the number of feet that will be covered in 55seconds, we will solve the equality operation;

If 105,600 feet = 1hour (3600secs)

x foot = 55secs

where x is the amount of feet it will cover in 55 seconds?

Cross multiply

3600 * x = 105,600*55

3600x = 5,808,000

divide both sides by 3600

3600x/3600 = 5,808,000/3600

x = 1613.3 feet (to the nearest tenth)

<em>Hence the amount of feet covered in 55seconds to the nearest tenth is 1613.3 feet </em>

The distance from Antville to Beetleton is 60 km.

serious [3.7K]

Answer:

i. Time = 2 hours.

ii. Average speed for the whole journey = 25 km/h

Step-by-step explanation:

Distance from Antville to Beetleton = 60 km

Mr. Caterpillar's speed = 30 km/h

Speed = $\frac{distance}{time}$

⇒ time = $\frac{distance}{speed}$

= $\frac{60}{30}$

= 2

time = 2 hours

It would take Mr. Caterpillar 2 hours to travel from Antville to Beetleton at that speed.

On his return journey, his average speed is 20 km/h. Therefore;

average speed for the whole journey = $\frac{30 + 20}{2}$

= $\frac{50}{2}$

= 25

average speed for the whole journey = 25 km/h
